In Germany August 18, 1933 516,448, filed February 17, 1931, describesand claims mechanism comprising an endless conveyor whereby bobbins areconveyed to positions facing the spindles or skewers of a winding frame,

and. means whereby, when the bobbins face the spindles, a relativemovement between the conveyor and spindles is caused to take place,causing the bobbins placed on the spindles, or donned, .the'dofiing ofthe'empty' tubes being performed automatically. The object of ourpresent invention is to simplify the mechanism and render .the same morecompact, at the same-time enabling the operation to be performed with aminimum of risk of damaging delicate bobbins.

. According to the invention an additional movement is imparted, namely,a movement whereby before and after the donning operationthe spindlesand the conveyor are placed at different levels, so that thelongitudinal movement of the which the conveyor occupies during thedonning operation. The additional movementreferred to may be made bythespindles, or by the conveyor itself. r

The advantages derived from this arrangement will be explainedhereinafter.

l- Three examplesof apparatus according to the invention are shown inthe annexed drawings, in Figs. 1 to 6, Figs. 7 and 8 and Figs. 9 and 10respectively.

Figs. 7 and 8 are sectional views of a second "embodiment of themachine, taken along one of the winding stations, showing the parts indifferent operative positions, and

-Figs.-9 and 10 are sectional views of a third embodiment of themachine, taken along one of the winding stations, showing the parts indifferent operative positions.

Referring first to the construction shown in Figs-,1 to 6, an endlessconveyor chain I works in a movable frame consisting of two brackets 2connected to eachother by channeled bars 3 Serial t.

7Clairns. (01.242-355) guiding the chain. Attached to the chain arecradles 4 for the bobbins 5, and the brackets carry an adjustable bar 6serving as an abutment for the bobbins, for the purpose of pushing themon to the spindles, which radiate from rotatable sleeves or hubs l. Thechain is driven by means of sprocket wheels 8. An arm 9 (Figs. 5 and 6)projects laterally from the chain I so that it strikes the downwardlydirected spindles in passing, and rotates the spindle holders. Theremaybe more than one such arm on the chain.

The brackets 2 are mounted by' means of rollers I 0 on rails I I,enabling the frame to be moved transversely'of the bank ofspindles. Thespindle holders 1 are mountdgona shaft I2 supported by bearings I3 fii:ed tovertical rods M, which are slidable in lief gs I5 fixed to themachine frame ds I4 rest on cams I6 fixed to a shaft I'Iv lq iatable inbearings I8 carried by a frame 7 member I9. The shaft I! has cranks 2!connectconveyor takes place at a level different from that ed by rods 22to the frame 2, 3, and it can have a crank handle 23 for rotating it byhand.

It will be seen that byrotation of the shaft I! the shaft I2 with thespindle holders can be raised and lowered. Figs. 1, 4 and 5 show the 2shaft I2 in its highest Ipos ition and from Fig. 4 it will be seen thatinf 'i this position the cradles 4 on the conveyor I can pass freelyunder bobbins 5 carried by spindles in a horizontal position over theconveyor. Fig. 1 shows the horizontal spindle without a bobbin thereon,but there is a bobbin 5 in the cradle 4 in front of the spindle.Rotation of the shaft I I then causes the cams IE to drop the spindleholder, so that the horizontal spindle is placed in line with the bobbintube, as shown in Fig. and the connecting rod 22 pulls the frame 2, 3towards the spindle holder, so that the bar 6 pushes the bobbin on tothe spindle, as shown in Fig. 3, whereupon the cams lift the spindleholder again and the 40 connecting rod 22 pushes the frame I, 2 back toits original position, as shown in Fig. 4.

The bobbin is held and guided by the cradle 4 during the whole operationof pushing it on to the spindle, and this is one of the advantagessecured, as compared with the arrangements shown in the above-mentionedearlier specification.

A single revolution of the cams lowers the bank of spindles into linewith the bobbin tubes,

'pulls the conveyor towards the spindles so that the bobbins are donned,and pushes the conveyor back and lifts the spindles so that the bobbinsthereon clear the cradles on the conveyor.

In the modification shown in Figs. and 8 the shaft I2 carrying thespindle holders is mounted in stationary bearings 24 fixed to the frame20, but the frame 2a, 3a carrying the conveyor la is vertically movableas well as horizontally movable. It rests on two cams 25, 26 fixed toshafts Z'l and IT respectively. These shafts have bearings in brackets28 and are connected to each other by: gear wheels 29, 30, 3|, the wheel29 being fixed to the shaft I1, the

wheel 36 to a shaft 32, and the wheel 3| to the shaft 21, The shaft Hcan be rotated by means of a hand crank 23, for which some suitableautomatic drive may be substituted. .Rotation of the shaft H causes theframe 211,311 to be raised and lowered, with the endless conveyor la. Itis shown in its highest position in Fig. 8 .1 with the bobbins in linewith the horizontal spindles directed towards them. Fig. '7 shows theframe 2a,, 3a in its lowest position. The shaft H has cranks 2! withrods 22 connecting them to' the frame 2a, 3a, so that in addition tobeing raised and lowered the frame, with the conveyor la and cradles 4,is moved transversely, the arrangement being such that when the bobbintubes are in line with the spindles the frame is pulled towards thespindles, whereby the bobbins are donned, whereupon the frame is pushedback and lowered. For pushing the bobbins on to the spindles each cradlehas an abutment 33 for the tip of the tube.

In the modification shown in Figs. 9 and 10 the shaft !2 carrying thespindle holders 1 likewise has fixed bearings, so that the frame 2, 3must'move up and down, in addition to'moving to and from the spindles.The frame 217, 3b in this case is mounted by means of rollers ill onbrackets 34, on which are tracks or runways for the rollers. Each ofthese runways is composed of four horizontal parts 35, 35, 31, 38, withinclined parts 39 and 40 connectingthe parts 35 and 38 respectively withthe parts 31 and 38. Whenthe rollers it rest on the parts 35, 36 theframe 21), 3b is at its lowest level, as shown in Fig. 9, and when it ispulled up' the inclined parts of the track on to the parts 31, 38 it isat its highest level, as shown in Figflo. The 'movement is impartedbpranks 2! on a shaft H, with rods 22 connec rig the cranks to the frame.

It will be clear, that the arrangement whereby the conveyor with thebobbin carriers or cradles is, in one position, at a level below thespindles on which bobbins haveibeen'placedenables the width of themachine from front te-rear; is substantially less than is the case.wherefthe withdrawal of the bobbin carriersfromjthe bobbins is effectedsolely by ahorizontal movement. This reduction of width facilitates theworkpf the operative and enables cop carriers or cradles of ample lengthto be used, so'that the bobbins are held securely While being conveyedalong the bank of spindles, and while being donned. The

The automaticdoffing of the empty tubes may be effected by means ofanyof the devices shown for that purpose in the specification of ourapplication Serial No. 516,448. Such doifing means are shown in Figs.7-10 of the instant disclosure, consisting of a fixed cam la adjacenteach spindle hub, whichengages the end of the empty bobbin tube 5a inthe course of the rotation of the shaft I2 with the hubs I mountedthereon, thereby stripping the tubes from the spindles.
